AKU Flyrock Mid GTX Black/Silver

AKU Flyrock Mid Gore-Tex (AK695) – Black/Silver

The AKU Flyrock Mid Gore-Tex in Black/Silver is a 402g mid-cut fast hiking boot built for technical days where the low Flyrock isn't enough. Gore-Tex Most Breathable waterproofing handles sustained wet conditions without impeding airflow on high-output ascents. The Vibram Megagrip + Traction Lug outsole delivers maximum friction on wet rock and fell ground at speed. AKU Dynamic Fit adjusts heel tension to your natural stride — climbing or descending — while the High Cushion High Rebound EVA midsole and Ortholite footbed absorb impact on big days. At 402g, it is 30g more than the Flyrock Gore-Tex low shoe (372g): the weight of the ankle support the mid-cut adds on more committing ground.

WHY YOU'LL LIKE IT

• Vibram Megagrip + Traction Lug outsole — the highest-friction Vibram compound holds grip on wet rock, muddy fell ground, and technical terrain at fast hiking pace where standard compounds lose traction
• Gore-Tex Most Breathable waterproofing — AKU's highest-breathability Gore-Tex lining keeps feet dry without trapping heat on high-output days, where a heavier membrane would create its own problem
• AKU Dynamic Fit — heel tension adjusts dynamically to match your stride through the full ascent-descent cycle, keeping the fit precise without manual lacing adjustments on the move
• 402g per half pair — 30g more than the Flyrock Gore-Tex low shoe (372g), giving mid-cut ankle support on technical and uneven terrain without significantly impacting pace
• UK 6–13 — AKU lasts run narrower than most UK footwear; if you have a wider foot or are between sizes, sizing up is recommended

BEST FOR

• Fast hikers who need ankle support on technical fell terrain and demanding descents where the low Flyrock Gore-Tex isn't sufficient — the Mid adds 30g for the stability that more committing ground requires
• High-mileage day hikers covering routes with mixed rock, wet moorland, and significant elevation change, where Vibram Megagrip traction and Most Breathable waterproofing outperform standard fast hiking compounds
• Hikers moving between trail and technical mountain terrain who want the Flyrock family's pace-focused construction in a mid-cut that handles more variable underfoot conditions
